In recent years, palladium‐catalyzed allylation has become the focus of much research. However, conventional homogeneous Pd catalysts face problems regarding their recovery, reuse, and cost, especially with respect to green chemistry principles. Herein, we present an overview of the development of catalytic allylation with various heterogeneous Pd catalysts, because they can be easily and conveniently recovered and reused. We also emphasize the use of different solid supports such as polymers, silica, and other hybrid supports to inspire future research in this promising field. Moreover, the unique effects of support surfaces for enhancing catalysis by immobilized heterogeneous Pd species are introduced.

亲核催化剂液相烯丙基化的异相负载钯催化剂

近年来，钯催化的烯丙基化已成为许多研究的重点。然而，常规的均相Pd催化剂在回收，再利用和成本方面面临问题，特别是在绿色化学原理方面。本文中，我们概述了使用各种非均相Pd催化剂进行催化烯丙基化的进展，因为它们可以轻松，方便地回收和再利用。我们还强调使用不同的固体载体，例如聚合物，二氧化硅和其他混合载体，以激发这一有前途的领域的未来研究。此外，介绍了载体表面通过固定化的异质钯物种增强催化作用的独特作用。
